Check the bag on your machine to see if it is more than half full. If it is, change the bag. Make sure the pre-motor and post-motor filters are clean. Detach the hose from the machine and turn on the unit. If the indicator stays green, the hose may be clogged. In this case, disconnect the hose from the unit and disconnect the attachment from the hose. Carefully insert a broomstick handle to remove any obstruction. If the bag indicator light is still red, please have your machine inspected at a local BISSELL Authorized Service Center.
